LONG NONLINEAR INTERNAL WAVES [PDF]

open access: yesAnnual Review of Fluid Mechanics, 2006
Over the past four decades, the combination of in situ and remote sensing observations has demonstrated that long nonlinear internal solitary-like waves are ubiquitous features of coastal oceans. The following provides an overview of the properties of steady internal solitary waves and the transient processes of wave generation and evolution ...

Weakly Nonlinear Internal Waves in Shear

Studies in Applied Mathematics, 1981
An evolution equation in a finite depth fluid for weakly nonlinear long internal waves is derived in a stratified and sheared medium. The equation reduces to the Korteweg‐deVries equation when the depth is small compared to the wavelength, and to the Benjamin‐Ono equation when the depth is large compared to the wavelength.

Nonlinear internal gravity wave beams

Journal of Fluid Mechanics, 2003
Based on linear inviscid theory, a two-dimensional source oscillating with frequency $\omega_{0}$ in a uniformly stratified (constant Brunt–Väisälä frequency $N_{0}$) Boussinesq fluid induces a steady-state wave pattern, also known as St Andrew's Cross, that features four straight wave beams stretching radially outwards from the source at angles $\pm ...

Nonlinear internal waves in the atmosphere

The Journal of the Acoustical Society of America, 1975
Nonlinear dispersive effects on the propagation of atmospheric internal waves are investigated. The finite amplitude buoyancy oscillation is analyzed to obtain an amplitude−dependent oscillation frequency. A nonlinear dispersion relation for finite−amplitude internal waves is derived. Its relation to the nonlinear buoyancy oscillation is discussed. The

Nonlinear internal wave interactions

AIP Conference Proceedings, 1981
We are presently engaged in the direct numerical calculation of the interactions among a set of random internal gravity waves. The calculations are in 2‐D using a pseudo‐spectral code of 128×128 spectral components. They are initialized using the Garrett‐Munk spectrum.
